A boat travels 160 miles in five hours (with a constant speed). How much Time will it take traveling 248 miles

Use cross multiplication:

160 248
—— = ——-
5 x

160x= 248(5)
160x= 1240
x = 7.75

It will take 7 h and 45 minutes to travel 248 miles!

160 miles divided by 5 hours is 32 mph. So if the boat goes 248 miles we divide it by 32 mph, to get 7.75 or 7 3/4 hours. Im pretty sure that is right. I hope this helps. If you find my reply very informative, i would appreciate it if you give me a brainliest. :)

Without multiplying, tell which is greater: 4/5 x 45 or 2/3 x 45. Explain.

Answer: It is 4/5 x 45

Step-by-step explanation: Hope i helped please mark brainliest!

I know there is suppose to be no multiplying but if you mulitply in your head 4/5 x 45 is 36 and 2/3 x 45 is 30

therefore, 4/5 x 45 is greater!
